I have a 1974 US spec 450SLC that I'm in the process of making less slow and less rusty. I've already done most the cosmetic stuff and now I have a set of subframes from a R107 that have the anti squat rear, a worn out LSD, and the fronts are ready to be reinforced. I don't know why it would be any different but I read somewhere that the R107 and C107 use different rear subframes.

I want to be able to take these down to bare metal and make them better than new before swapping in all new suspension at both ends without having to down my car for too long. Then I'll be on the hunt for some more power and a better transmission.
